Symbol Error Rates of Maximum-Likelihood Detector: Convex/Concave Behavior and Applications
— Convexity/concavity properties of symbol error rates (SER) of the maximum likelihood detector operating in the AWGN channel (non-fading and fading) are studied. Generic conditi...

ROPAS: Cross-Layer Cognitive Architecture for Mobile UWB Networks
The allocation of bandwidth to unlicensed users, without significantly increasing the interference on the existing licensed users, is a challenge for Ultra Wideband (UWB) networks....

On Scaling Laws of Diversity Schemes in Decentralized Estimation
This paper is concerned with decentralized estimation of a Gaussian source using multiple sensors. We consider a diversity scheme where only the sensor with the best channel sends...

Transmission Over Slowly Fading Channels Using Unreliable Quantized Feedback
We study the problem of maximizing the expected rate over a slowly fading channel with quantized channel state information at the transmitter (CSIT). This problem has been recentl...

Asynchronous distributed power and rate control in ad hoc networks: a game-theoretic approach
This paper analyzes distributed asynchronous power and rate control for wireless ad hoc networks. Importantly, all network transmitters are considered to be independent of any mana...
